I'm also looking for documentation or code example. Did you manage to find any @gypsicoder ?

To use sendToContentScript to send from background message to context you can send a message in the following style

// Send a message to the content script
sendToContentScript({
    body: {
        message: "Hello from the background script",
    },
    name: 'context name'
});

name and body are required before of interface, but the content of the body can be anything you want.

However, I only manage to receive the message using native chrome runtime like

chrome.runtime.onMessage.addListener(function (message) {

    if (message.name === "context name") {
        console.log("context name", message.body);
    }

    console.log("[APP] Received message from background script:", message);
});

I'll much prefer if there is a way via plasmo to detect and use a universal runtime for other browsers such as Firefox and Safari, instead of hardcoding chrome runtime to have a much easier way to build for other browsers.

I think this repo has what you want.

I think we can find the perfect example here
PlasmoHQ/examples#31
Though I don't see the content script part in main branch
